Introduction. FRC (fiber-glass reinforced composite) posts with
reinforced composite fibers are introduced as an alternative for many
conventional materials. Endodontically treated teeth are known to
present a higher risk of biomechanical failure than vital teeth. The
choice of an appropriate restoration for endodontically treated teeth is
guided by strength and esthetics.
The aim of this study is to present the use of new item nonmetallic
systems in restaurative dentistry. Physical characteristics given by
manufacturer (Ivoclar Vivadent, Schaan, Liechtenstein), show exellent
results, are identified with tooth structure in regard of flexure
strength, module elasticity, water absorbtion and clear radiopacity. The
use of nonmetallic posts is easy, fast, safe and reliable.The research
of several authors has shown exellent results of newer nonmetallic
systems. They have the following features: physical properties similar
to dentin, maximum retention with little removal of dentin from the root
canal, distribution of functional stress even along the root surface,
material compatibility with core, high esthetic qualities, minimal
stress during placement and cementation, resistance to displacement,
good core retention, easy retrievability, ease of use, safety and
reliability, and reasonable cost.
Conclusion. Nonmetallic fiber-glass posts contributed greatly into the
development of new post and core systems and improved the quality of
prosthetic treatment. In comparison with former conventional materials
and post and core systems, FRC posts demonstrate significant preference
for new technological accomplishments.
